Spot on, in 2005 when I lived in (among other places) Sudan, Sourceforge
would block certain downloads (but not the project site).  That said it
was trivial to bypass the restrictions then.

I don't think it's related to these sanctions but to the Great
Firewall of China, but sourceforge downloads are also blocked in
China. Also quite easy to bypass though.

Another concern is sourceforge being attacked and a backdoored client uploaded.
Most people don't check signatures and I seem to recall sourceforge having some
vulnerabilities stemming from their "your own website on sourceforge" feature.
It looks like Github takes security a little bit more seriously.
Probably the best is to ask for free hosting from a reputable security conscious
bitcoin enthusiast but that basically means Tux and he's already an SPOF in the
coineverse.

Thanks,

[Bitcoin-development] Hosting of compiled bitcoin client

[Kyle Henderson]

[-- Attachment #1: Type: text/plain, Size: 383 bytes --]

Hi team,

Given that sourceforge has shown to restrict access to a number of
countries at the request of the USA, would hosting of the compiled client
on https://github.com/bitcoin/bitcoin/downloads be an alternative that
would be considered?

It seems like a logical alternative to me that requires little effort as it
is already in use as the code repository.

Kind regards,

Kyle

This needs some clarification. If the USA has "requested" it, then presumably 
there's some legality involved, and our US developers shouldn't be made liable 
for it. The specific reason SourceForge has restricted access should be made 
known so non-US developers (or gitian builders) can evaluate their own laws 
and hopefully at least one will be in a jurisdiction that allows it.
But GitHub is also US-located, so hosting it there may be a problem too.

Being an international team I'm pretty sure we can find someone who is in a
more permissive country.
Would someone knowledgeable point us to the specific laws, so that we can
look it up in our respective jurisdiction?

Regards,
Chris

The only restrictions I'm aware of are the EAR restrictions on the
export of cryptography.

These are generally not applicable to us for two reasons. One is that
we only use cryptography for authentication, which is explicitly
exempted:
http://www.bis.doc.gov/encryption/question2.htm

The other is that since Bernstein vs US
(http://en.wikipedia.org/wiki/Bernstein_v._United_States) there has
been absolutely no enforcement attempts against open source projects
as the precedent creating holding there makes it clear that these
regulations cannot inhibit the publication of source code.

Perhaps someone could make a little noise about binaries, but it would
be pure pretext: Especially since with the deterministic build process
we use anyone can produce bit-identical binaries (thus allowing builds
by untrusted third partities to be just as trustworthy as the official
ones).

> "more permissive country"

This made me laugh. It's hard to find places with better effective law
for most online and internet things.  Many places copy the US's
statutes (either cargo culting, or as part of treaty compliance) but
do so without also copying our legislative history which is
/generally/ highly protective.  For example, Australia has copied the
US munitions regulations exactly, but has no analog of Bernstein v. US
to limit the government's power.

Unfortunately sourceforce was rather vague about what regulations they
believe they're enforcing:
http://sourceforge.net/blog/clarifying-sourceforgenets-denial-of-site-access-for-certain-persons-in-accordance-with-us-law/

So unless someone has already done it, I'll get in touch with the EFF
and find out if they're aware of any particular precautions we should
take here.

Re: [Bitcoin-development] Hosting of compiled bitcoin client

[Mike Hearn]

The laws in question are OFAC sanctions:

http://en.wikipedia.org/wiki/Office_of_Foreign_Assets_Control

The specific acts that enable this are varied. In theory they apply to
any US citizen or resident. The issue is not cryptography, it's "trade
with sanctioned countries", period, where making files available to
download is considered trade.

For Bitcoin to be available in these places, the sites and download
mirrors would need to be hosted outside the USA by non-citizens. EU
sanctions are primarily financial at this time, as far as I know there
are no attempts to prevent people from serving data to Iran.

Example of places where there are no sanctions in effect: Switzerland.
Unfortunately datacenter space in Zurich is quite expensive (as is
everything here).

I would not ever describe OFAC as "effective law". The SDN list has
repeatedly been found unconstitutional, representing as it does a
complete evasion of the judicial system. If you end up on the
sanctions list no evidence is required, no process is followed and no
appeals are possible. The list itself assumes names are globally
unique.
